如何将数据网格嵌套在另一个数据网格中以显示字符串的子数组？

Question

我正在寻找的行为是，当单击一行时，另一个数据网格显示来自同一源的字符串的子数组。相反，我得到的是包含每个字符串长度的行。

XAML

<DataGrid Name="dg">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Code" Binding="{Binding Code}" />
        ...
    </DataGrid.Columns>

    <DataGrid.RowDetailsTemplate>
        <DataTemplate>
            <DataGrid Name ="dg2"  ItemsSource="{Binding Emails}" RowDetailsVisibilityMode="VisibleWhenSelected"  >
                <DataGrid.Columns>
                    <DataGridTextColumn Header="Email" Binding="{Binding Email}" />
                </DataGrid.Columns>
            </DataGrid>
        </DataTemplate>
    </DataGrid.RowDetailsTemplate>
</DataGrid>

的ItemsSource

<Job GUID="5a790ed3-e3a3-4251-9906-36cfdcdc2fb2">
    <Code>something</Code>
    <Emails>
      <Email>gnhfgj</Email>
      <Email>gjfjgfj</Email>
    </Emails>
</Job>
<Job GUID="5a790ed3-e3a3-4251-9906-36cfdcdc2fb2">
    <Code>somethingelse</Code>
    <Emails>
      <Email>email</Email>
    </Emails>
</Job>

C＃

string xmlFileName = "Jobs.xml";

XmlSerializer reader = new XmlSerializer(typeof(List<Job>));
StreamReader file = new StreamReader(xmlFileName);
List<Job> load = (List<Job>)reader.Deserialize(file);

dg.ItemsSource = load;

找到答案。这直接绑定到字符串。

<DataGridTextColumn Header="Email" Binding="{Binding}" />
